摘要： An approach identifies an amount of high order bits used to store a memory address in a memory address field that is included in a memory. This approach calculates at least one minimum number of low order bits not used to store the address with the calculation being based on the identified amount of high order bits. The approach retrieves a data element from one of the identified minimum number of low order bits of the address field and also retrieves a second data element from one of the one of the identified minimum number of low order bits of the address field.

摘要： Techniques for simulating exclusive use of a processor core amongst multiple logical partitions (LPARs) include providing hardware thread-dependent status information in response to access requests by the LPARs that is reflective of exclusive use of the processor by the LPAR accessing the hardware thread-dependent information. The information returned in response to the access requests is transformed if the requestor is a program executing at a privilege level lower than the hypervisor privilege level, so that each logical partition views the processor as though it has exclusive use of the processor. The techniques may be implemented by a logical circuit block within the processor core that transforms the hardware thread-specific information to a logical representation of the hardware thread-specific information or the transformation may be performed by program instructions of an interrupt handler that traps access to the physical register containing the information.
摘要翻译：用于模拟在多个逻辑分区（LPAR）中独占使用处理器核心的技术包括提供响应于LPAR的访问请求的硬件线程依赖状态信息，所述LPAR反映了LPAR访问硬件线程相关的独占使用处理器信息。如果请求者是在低于管理程序权限级别的特权级别下执行的程序，则转换响应于访问请求而返回的信息，使得每个逻辑分区将处理器视为处理器的独占使用。这些技术可以由处理器核心内的逻辑电路块来实现，其将硬件线程特定信息转换为硬件线程特定信息的逻辑表示，或者可以通过将访问陷阱的中断处理程序的程序指令执行物理寄存器包含信息。

摘要： A mechanism is provided for transparently consolidating resources of logical partitions. Responsive to the existence of the non-folded resource on an originating resource chip, the virtualization mechanism determines whether there is a destination resource chip to either exchange operations of the non-folded resource with a folded resource on the destination chip or migrate operations of the non-folded resource to a non-folded resource on the destination chip. Responsive to the existence of the folded resource on the destination resource chip, the virtualization mechanism transparently exchanges the operations of the non-folded resource from the originating resource chip to the folded resource on the destination resource chip, where the folded resource remains folded on the originating resource chip after the exchange. Responsive to the absence of another non-folded resource on the originating resource chip, the vitalization mechanism places the originating resource chip into a deeper power saving mode.

摘要： Multiple machine state registers are included in a processor core to permit distinction between use of hardware facilities by applications, supervisory threads and the hypervisor. All facilities are initially disabled by the hypervisor when a partition is initialized. When any access is made to a disabled facility, the hypervisor receives an indication of which facility was accessed and sets a corresponding hardware flag in the hypervisor's machine state register. When an application attempts to access a disabled facility, the supervisor managing the operating system image receives an indication of which facility was accessed and sets a corresponding hardware flag in the supervisor's machine state register. The multiple register implementation permits the supervisor to determine whether particular hardware facilities need to have their state saved when an application context swap occurs and the hypervisor can determine which hardware facilities need to have their state saved when a partition swap occurs.

摘要： A mechanism is provided in a logically partitioned data processing system for controlling depth and latency of exit of a virtual processor's idle state. A virtualization layer generates a cede latency setting information (CLSI) data. Responsive to booting a logical partition, the virtualization layer communicates the CLSI data to an operating system (OS) of the logical partition. The OS determines, based on the CLSI data, a particular idle state of a virtual processor under a control of the OS. Responsive to the OS calling the virtualization layer, the OS communicates the particular idle state of the virtual processor to the virtualization layer for assigning the particular idle state and wake-up characteristics to the virtual processor.

摘要： A mechanism is provided for temporarily allocating dedicated processors to a shared processor pool. A virtual machine monitor determines whether a temporary allocation associated with an identified dedicated processor is long-term or short-term. Responsive to the temporary allocation being long-term, the virtual machine monitor determines whether an operating frequency of the identified dedicated processor is within a predetermined threshold of an operating frequency of one or more operating systems utilizing the shared processor pool. Responsive to the operating frequency of the identified dedicated processor failing to be within the predetermined threshold, the virtual machine monitor either increases or decreases the frequency of the identified dedicated processor to be within the predetermined threshold of the operating frequency of the one or more operating systems utilizing the shared processor pool and temporarily allocates the identified dedicated processor to the shared processor pool.

摘要： A method, system and computer-usable medium are disclosed for managing power consumption in information processing systems. Processing resources are successively folded, allowing them to be placed into deeper and deeper power saving states while maintaining the ability to respond to new processing loads without exposing the latency of the deeper power saving states as they are unfolded. Before a deeper power saving state can be used, there must be sufficient processing resources in the prior power saving state to mask the latency of bringing a processing resource out of the deeper power saving state.

摘要： An information handling system includes instruction processing nodes in respective physical partitions. A communications bus couples two information processing nodes together. Each node includes hardware resources such as CPUs, memories and I/O adapters. Prior to a command to merge the physical partitions, the communication bus exhibits a disabled state such that the two information processing nodes are effectively disconnected. After receiving a command to merge the physical partitions, the system enables the communication bus to effectively hot-plug the two nodes together. A modified master hypervisor in one node stores data structures detailing the hardware resources of the two nodes. The modified master may assign resources from one node to a logical partition in another node.

摘要： Controlled partition shut-down is provided within a shared memory partition data processing system including a shared memory partition, a paging service partition, a hypervisor and a shared memory pool within physical memory. The hypervisor manages access to logical pages within the pool and page-out of pages from the pool to external paging storage via the paging service partition. A respective paging service stream exists between the paging service partition and hypervisor for each shared memory partition, with each stream including a stream state. The control method includes: responsive to a shut-down initiating event, notifying the paging service partition to shut down, and determining whether a shared memory partition is currently active, and if so, signaling the hypervisor to complete paging activity for the active memory partition and waiting for its stream state to enter a suspended or a completed state before automatically shutting down the paging service partition.
